What this tool does
Extract JS Web Locks Calls scans pasted JavaScript as text, lists navigator.locks.request and navigator.locks.query usage with lock names when literal strings are present, removes duplicate rows, and runs locally in your browser.
Common use cases
Extract Web Locks API calls from pasted JavaScript, TypeScript, offline app helpers, concurrency code, tests, or copied browser source before synchronization, migration, stale-task, or release QA review.
Use Extract JS Web Locks Calls when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste JavaScript, TypeScript, concurrency code, offline-app helpers, tests, or copied browser source that may use the Web Locks API.
- Choose whether duplicate API rows should be removed and whether extracted text should be normalized for comparison.
- Review lock names and lock-query usage with source-line context, then copy the list for concurrency QA, migration notes, release review, or documentation.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
